Another approach is to point the form submission back to the original form
- where the processing is done at the top and if the submission SUCCEEDS
you can cflocate somewhere else. If it fails for whatever reason, the form
is presented again, with non-conforming values removed, but the remaining
fields have their data intact (<INPUT TYPE="text" NAME="field"
VALUE="#value">). This is similar to the way you would use the same form
template for adding and editing a record...
Then you don't have to relay on browser issues at all AND the feedback to
the user is immediate and obvious. Especially when you can highlight the
errors...
